Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Fig. 1-3 show the preferred embodiment of the utility model discloses a novel cabinet lock, including handle 10, the handle pivot 20 of being connected with handle 10, spacing ball 30, spring bolt 40 and drive arrangement, the rotatory cambered surface of handle pivot 20 is equipped with one with the arc breach of spacing ball 30 looks adaptation, drive arrangement is connected with the transmission of spring bolt 40 and stretches out and draws back in order to drive spring bolt 40, spring bolt 40 stretches out and draws back and imbeds in order to promote spacing ball 30 the embedding of arc breach or release embedding the spacing ball 30 of arc breach. Namely, the limiting ball 30 is inserted into the arc notch of the handle rotating shaft 20 for blocking, so that the handle rotating shaft 20 cannot rotate, and the locking state is achieved, as shown in fig. 3; or the driving device drives the lock tongue 40 to release the limiting ball 30, namely, the handle rotating shaft 20 is rotated, so that the limiting ball 30 of the arc-shaped notch is extruded out to realize unlocking, as shown in fig. 2; the assembly is simple, the occupied space is small, the unlocking resistance is small, and the lock is smooth.

The initial position of limiting ball 30 is installed at the lower edge of the arc-shaped notch, and the lower half part of limiting ball 30 opposite to the arc-shaped notch is arranged on the moving path of locking bolt 40. The limiting ball 30 is limited and mounted at the lower edge of the arc-shaped notch through a limiting seat, namely, the limiting ball 30 can only move at the position of extruding into or out of the arc-shaped notch; as shown in the figure, the arc-shaped notch is arranged right below the rotating arc surface of the handle rotating shaft 20, the limiting ball 30 is arranged at the lower edge of the arc-shaped notch, when the driving device drives the locking bolt 40 to move, the locking bolt 40 pushes the lower half part of the limiting ball 30 to extrude into the arc-shaped notch, the handle rotating shaft 20 is limited through the clamping position of the limiting ball 30 and the arc-shaped notch, and the handle rotating shaft 20 is difficult to rotate to open the lock body; on the contrary, when the driving device drives locking bolt 40 to return to the initial state, that is, locking bolt 40 moves backward to not contact with limiting ball 30, locking bolt 40 releases the limiting fixation on limiting ball 30, and at this time, the user only needs to slightly screw handle 10, and by rotating handle spindle 20, the inclined plane of the arc-shaped notch pushes limiting ball 30 to disengage from handle spindle 20, that is, handle 10 can rotate to open the lock body.

The driving device comprises a motor 51, a transmission shaft 52 and a spring 53, one end of the transmission shaft 52 is in transmission connection with the motor, the other end of the transmission shaft 52 is fixedly connected with a first pin of the spring 53, a second pin of the spring 53 is fixedly connected with the lock tongue 40, the motor 51 drives the transmission shaft 52 to rotate so as to compress or extend the spring 53, and the spring 53 drives the lock tongue 40 to move. If motor 51 drives transmission shaft 52 to rotate clockwise, the first leg of spring 53 is driven to rotate clockwise, and at this time, the first leg of spring 53 is compressed to form elastic potential energy, and when the elastic potential energy is greater than the frictional resistance of locking bolt 40, locking bolt 40 is driven to move towards motor 51; conversely, when the motor drives transmission shaft 52 to rotate counterclockwise, the first leg of spring 53 is driven to rotate counterclockwise, and at this time, spring 53 is released to extend, so that lock tongue 40 is bounced away from motor 51; after the locking tongue 40 of this embodiment moves a certain distance towards the motor 51, the limiting ball 30 will be squeezed, so that the limiting ball 30 is squeezed into the arc-shaped notch, and the handle spindle 20 is further clamped, so that the handle 10 cannot rotate, as shown in fig. 3; when locking bolt 40 is rebounded away from motor 51 and limiting ball 30 is released, the user can rotate handle 10, and after limiting ball 30 is pushed out by the slope of the arc notch of handle spindle 20, handle 10 can rotate freely to open the lock body.

Preferably, the limiting ball 30 is made of a metal material, and the surface of the metal material is smooth, so that the handle 10 can be conveniently rotated to extrude the limiting ball 30; the limiting ball 30 is specifically a steel ball.

The handle rotating shaft 20, the limiting ball 30, the locking tongue 40 and the driving device are mounted between the bottom shell 62 and the face shell 61, and the handle 10 penetrates through the face shell 61 to be connected with the handle rotating shaft 20. And a hardware middle shell 63 is also arranged between the bottom shell 62 and the face shell 61. Preferably, the device further comprises a main control switch lock module electrically connected with the driving device; the main control switch lock module comprises a fingerprint identification submodule and/or a password identification submodule, namely the driving device is driven to work by a corresponding unlocking signal, and the unlocking signal can be a correct fingerprint instruction or password instruction and the like.

To sum up, novel cabinet lock including the handle, with handle pivot, spacing ball, spring bolt and drive arrangement that the handle is connected, the rotatory cambered surface of handle pivot be equipped with one with the arc breach of spacing ball looks adaptation, drive arrangement with the spring bolt transmission is connected with the drive the spring bolt is flexible, the spring bolt is flexible in order to promote spacing ball embedding and screens arc breach or release embedding the arc breach spacing ball. Therefore, the utility model discloses the assembly is simple, and occupation space is little, and the resistance of unblanking is little and in the same direction as smooth.

Naturally, the present invention can be embodied in many other forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be made by one skilled in the art without departing from the spirit or essential attributes thereof, and it is intended that all such changes and modifications be considered as within the scope of the appended claims.
